3.15.0.3

Release date 2026/08/10

Bugfix

  • Security: Fixed CVE-2026-14917 in the SAML plugin by always validating the samlp:Response signature when idp_certificate is configured correctly, and logging a warning if misconfigured. This prevents a crafted unsigned SAML response from silently bypassing authentication when validate_assertion_signature is set to false.

3.14.0.12

Release date 2026/08/10

Bugfix

  • Security: Fixed CVE-2026-14917 in the SAML plugin by always validating the samlp:Response signature when idp_certificate is configured correctly (and logging a warning if misconfigured), preventing a crafted unsigned SAML response from silently bypassing authentication under configurations that set validate_assertion_signature to false.

3.13.0.9

Release date 2026/08/10

Bugfix

  • Security: Fixed CVE-2026-14917 in the SAML plugin by always validating the samlp:Response signature when idp_certificate is configured correctly (and logging a warning if misconfigured), preventing a crafted unsigned SAML response from silently bypassing authentication under configurations that set validate_assertion_signature to false.

3.13.0.0

Release date 2025/12/18

Bugfix

  • Fixed an issue that caused a crash when the NameID Format was set to Unspecified.

3.12.0.11

Release date 2026/08/18

Bugfix

  • Hardened signature validation against XML Signature Wrapping. The plugin now checks that the signature Reference URI is a same-document fragment that names the ID of the element it digests and consumes, so a signature can no longer be bound to a different element than the one that provides the identity. A response whose reference URI is empty or not a same-document fragment is now rejected.
